Case Study: How a Premium IV Clinic Doubled Client Retention Rate with Howa NAD+ Client retention is the lifeline of an IV clinic. Our collaboration with a high-end clinic showed that after switching to Howa's injectable-grade NAD+ (purity ≥99%, endotoxin <0.2 EU/mg), their client retention rate doubled within 6 months. The key reason: higher purity and safety delivered a more significant energy boost and cognitive improvement experience, greatly increasing clients' willingness to repurchase. Choosing reliable raw materials means choosing stable business returns.sales@horwats.com +86 19052754932(whatsapp) #SuccessStory #NADTherapy #RetentionRate #IVClinic #Horwats
